from PIL import ImageFile as PILImageFile

p = PILImageFile.Parser()

#Parser the data
for chunk in content.chunks():
    p.feed(chunk)
try:
    image = p.close()
except IOError:
    return None
#Here the model is RGBA
if image.mode != "RGB":
    image = image.convert("RGB")


它总是卡在这里:

image = image.convert("RGB")

File "C:\Python25\Lib\site-packages\PIL\Image.py" in convert
  653.         self.load()
File "C:\Python25\Lib\site-packages\PIL\ImageFile.py" in load
  189.                     s = read(self.decodermaxblock)
File "C:\Python25\Lib\site-packages\PIL\PngImagePlugin.py" in load_read
  365.         return self.fp.read(bytes)
File "C:\Python25\Lib\site-packages\PIL\ImageFile.py" in read
  300.             data = self.data[pos:pos+bytes]

Exception Type: TypeError at
Exception Value: 'NoneType' object is unsubscriptable

最佳答案

这是由于PIL中close的错误编码导致的,这是一个错误。

编辑文件(系统上的路径可能不同):

须藤vi /usr/lib64/python2.6/site-packages/PIL/ImageFile.py

在线283修改:

def close(self):
    self.data = self.offset = None


更改为:

def close(self):
    #self.data = self.offset = None
    self.offset = None


就是这样,注释掉损坏的代码,添加正确的行,然后保存文件。完成所有操作,只需运行以前失败的程序即可,现在就可以运行。
